Maintaining Temperatures Inside Of A Shipping Container

At KiwiBox, we are often asked ‘what’s the best way to maintain the temperature of my shipping container?’ With cold storage options a key part of the service that we offer, we’re definitely experts on the subject! There’s no need to ask anyone else.

Active cooling, passive cooling and insulation – there are a few things to think about when you’re looking at a cold storage container and a number of ways in which you can maintain your desired temperature within. Read on for a bit more information about the different methods of container cooling available and figure out what the right choice is for your needs.

Type of Container

Lets take a look at standard shipping containers just to get an idea of the main issues that they have in terms of cooling. Standard containers are prone to wear and tear, especially around the doors, and will let air leaks and, subsequently, condensation inside. This can cause all kinds of problems and, combined with thin container walls, it is nearly impossible to maintain a desired temperature within.

Insulated containers have low heat-transfer walls that cause less changes in temperature from sun exposure and, conversely, overnight when the external climate cools. For short trips, insulated containers might not even require an internal active or passive cooling system, instead being “pre-cooled” before the journey begins. While insulated containers are effective at maintaining temperature, it won’t last forever. Long-term, long-distance journeys will require a cooling system.

Types of Refrigeration Systems

Passive cooling systems use phase change materials to maintain desired temperatures. While passive cooling systems are reasonably cheap to run, they aren’t the most effective method of cooling. However, with a bit of planning, passive refrigeration systems are ideal for transportation.

Active cooling systems like compression systems and air conditioners use power or generators to maintain the temperature within the box. Thermostats can be set to a very specific number, which makes an active cooling system ideal if your storage needs are quite particular or over a longer period of time. Active cooling systems are also a better option if you are planning on using your container for static, on-site storage as you won’t have to keep replacing the phase change material as it gets used.

These are some of the basics when it comes to maintaining a constant temperature inside your shipping or storage container. You’re constantly fighting changes in the environment outside your container to keep your cargo and stock cool, but with the right container and the right cooling system it’s easy to make a shipping container into the perfect cold room and storage option for your business.
